Title: Electrode construction of surface acoustic wave filter
Inventor: TABUCHI TOYOJI
IPC: H03H9/25
Filed: 1981-11-20
Abstract: PURPOSE:To make the reflecting characteristics and the etching conditions compatible with each other, by connecting all conductor stripes of a reflector electrically and opening either one end of each conductor stripe at least for every other stripe. CONSTITUTION:Since open ends exist through the construction between cross type and short-circuited slit type, the etching liquid can be impregnated well and since the short-circuited slit exists, a reflector not affecting the reflecting characteristics can be attained. In figures (a) and (b), one end of the conductor stripe is opened at every other stripe and in figure (c), the two stripes are taken as open ends. Since the distance (t) of the open end can be selected freely independently of the center frequency, the distance can be determined depending on the impregnation of the etching liquid. In figure (d), the middle of the conductor stripes opened alternately is connected and the decrease in the reflection characteristics due to the increase in the open end can be prevented.
